hsearch and the ENTRY structure

[Leslie Chaim]

Hello,

I'm trying to use the hsearch() routines from search.h and I have some problems.

First, I get
cc: "test.c", line 64: error 1588: "ENTRY" undefined:(

I did include what am I missing here?


Second, the WARNING section of the man page indicates:

" Only one hash search table can be active at any given time."

Does that mean that the internal table is global? Just want to verify, and if so, can I do a hcreate(nel) in foo() and then do a hsearch(item,ENTER) in bar() and hsearch(item,FIND) is baz()?

Finally, is there any way around this limitation?


Thanks in advance,
Leslie

Well, I looked at the header file in /usr/include/search.h.

Much to my surprise I found there is a:

#ifdef _INCLUDE_XOPEN_SOURCE
...
#endif /* _INCLUDE_XOPEN_SOURCE */

In fact the example given in the manpage does not work unless you:

#define _INCLUDE_XOPEN_SOURCE

I am still looking for the other questions.

Regards,
Leslie
